Any change made to improve window insulation performance can make a significant difference in the energy that is lost through the building envelope.

With solar heat gain reductions of up to 75% (equaling average energy cost savings of between 5% and 15%), window film improves insulating performance of a commercial building’s windows. In fact, the newest low-e window films can improve window insulating performance by as much as 92%. In many cases, building owners and facilities managers receive a complete ROI on window film within three years (or less with utility rebates).

Vornado Realty Trust in New York estimates that between 60% and 80% of the energy used in its office buildings is actually consumed by tenants within their own office spaces. The company has found that, by providing access to real-time energy use data, its tenants work harder to identify and change wasteful energy practices.

This principle is playing out across the globe, as more and more organizations are (more…)

Letting the proper amount of daylight into a space can be a complicated process. Although windows provide much-appreciated and beneficial views to the outdoors, they can also cause uncomfortable indoor temperatures, glare, fading, and high utility bills.

Clovis Unified School District’s Buchanan High School staff members experienced this dilemma firsthand. Built in 1993 in Clovis, California, the 440,000-square-foot two-story building still had its original, single-glaze, non-tinted windows. The district’s maintenance department was noticing more complaints about (more…)
